The Dialga Deck is the fifth Half Deck of cards released during the PCG Series of the Korean Pokémon Trading Card Game. Available alongside the Palkia Deck starting August 19, 2010, it was designed to bolster the Pokémon evolutionary families included within the main expansion Collapse of Time & Space.
As the name suggests, the Half Deck centers around the Temporal Pokémon, Dialga, and the Metal-type. Also included within the Half Deck are Lightning-type prints of the Magnezone family, providing alternate evolutionary strategy for players wishing to utilize the main expansion's Metal-type Magnezone LV.X, as well as the Fighting-type, which was only just reintroduced to the Korean Card Game in the main expansion. Much like each other release during the Korean PCG Series, the deck pulls cards from Diamond & Pearl to Platinum. The two Trainer cards are reprints from the first two extension sets, Start of an Adventure and Burning Confrontation.
The Half Deck came packaged with a small rulesheet, damage counters, and playmat. The only Holofoil card in the Half Deck is Dialga.
